I not so sure whether this kind of question had been asked before, but I'm having problem on deciding how many cores should I put for my data nodes.
I somehow know how many RAM or disk space I should assign, but for CPU cores, I not entirely sure.
Is the more better? Or even 4 cores should be enough for a typical data nodes?
What are the factors I should look at in determining how many CPU cores needed in data nodes?
Does the amount of CPU cores will affect concurrently how many search request can a data node work on?
